I'm writing a little javascript application in which users need to be able to choose an image from an "image library" and then choose the color of said image. There will be a massive number of images and a massive number of colors, and I would really love if I did not have to make each color of each image. Instead, I was hoping to be able to take a png and swap the transparent and visible elements, so that I can just put a solid block of color behind it to change the color. Does anybody know of a good way to quickly do this (I have adobe design premium 5.5)? Thanks in advance!
